从守恒原理出发,在考虑温度引起空气密度变化、等压和小密度差近似的前提下,导出了描述风流紊流状态热量交换的数学模型。采用紊流粘性系数模型,封闭方程组,建立了一种新风流热量交换的数学模型——场模型。
Based on the conservation principle, the mathematical model describing the heat exchange in the turbulent flow of the wind flow is derived on the premise of temperature-induced changes in air density and equal pressure and small density difference. By using turbulent viscosity coefficient model and closed equations, a mathematic model - field model for the heat exchange of fresh air flow was established.
